Mt. Apetite consists of gravel roadway/ATV trail with single-track trails looping back and forth across the main road. Take the trails on the left to get started, and follow them thru the woods, back to the main road. Then cross the main road and follow the trails to the other side, etc. Most trails are hilly and moderately difficult, there are a few difficult technical sections (crazy steep, big rocks & logs).
From downtown Auburn, head out on Minot Avenue, past the intersection with Court St, Manley St, and Hotel Rd. After the Hotel Rd traffic light, turn Right onto the next road, Garfield. Turn left into the little league fields, then park your vehicle. Bike past the military facility, through the gate marked "pedestrians welcome," and straight to join the trail network.
